Firstly please excuse my ignorance on this subject.

I have started making brackets out of 40x6 flat bar and I am looking at advice how to speed up the drilling process. I currently drill 4 x holes using a 5.5mm HSS countersink bit. It works fine but for the volume we need to do I need to try and speed the process up a lot if possible.

All suggestions greatly appreciated
